SEPARATING APRON FOR VINERS.

Application filed April 26, 1920. Serial No. 376,797.

To all whom it may concern: 7

Be it known that I, FRANK HAMACHEK, a citizen of the United States, and resident of Kewaunee, in the county of Kewaunee and State of \Visconsin, have invented new and useful Improvements in Separating Aprons for Viners, of which the following is a description, reference being had'to the accompanying drawings, which are a part of this specification.

This invention relates to separating aprons for viners or pea vine threshing machines and the like and has for its object to prevent the loss of peas with the chaff and to prevent injury of the peas.

)ne purpose of the invention is to provide the separating apron with a raised ridge at each edge that will prevent peas from rolnng oif of the apron. v

Another purpose of the invention is to provide inclined guarctboards overhang ing the edges of the inclined apron, said guard-boards being arranged with their edges diverging so as to spread the chaff and peas over the apron and avoid clepositingthern in single lines thereon.

Another purpose of the invention is to provide for the discharge of matter that may find its way beneath the apron and prevent it from falling upon the return bight of the apron. 7

Another purpose of the invention is to provide a discharge conveyor for conducting the chaff away from the apron, with means for scraping the dirt from the apron and preventing the dirt and chaff from falling on the conveyer chains.

With the above and the invention consists .in the separating apron for viners as herein claimed and all equivalents.

Referring in which like characters of reference indicate the same parts in different views:

Fig. 1 is a transverse sectional view of a viner, showing in longitudinal section the separating apron constructed in accordance with this invention;

Fig. 2 is a plan view of the separating apron;

Fig. 3 is a transverse sectional view of one edge of the separating apron and the parts associated therewith;

Fig. i is an enlarged sectional. viewjof one edge of the separatingapron, showing other objects in view to the accompanying drawings the construction of the flexible head or ridge formed thereon. i v

In these drawings, 10 indicates a screen drum rotatably mounted in a frame 11 on rollers 12, as usual, and containing rotating heaters 1.3 for threshing pea vines or the like. The loose peas threshed from the vines, together with a quantity of chaff and dirt, fall through the screens of the screen drum 10 upon an inclined upwardly traveling endless separating apron 14 which carries the dirt and chaff upwardly, away from the loose peas which roll downward.-

ly thereon into collecting boxes, not shown.

To facilitate the separation of the peas from the chaff and dirt the apron is given an irregular movement by passing it around rollers 15 and 16 which are angular in cross section and one of which is suitably driven.

In order to keep the apron spread and prevent it from creeping and bunching it is provided at intervals with cross-slats 17 extending from one edge to the other on its under face and these slats, as well as the edge of the apron, bear on run-boards 18 secured to the side frames 19, which are suitably fastened to the frame 11. As

seen in Fig. 3, the run-boards 18 are secured-to the side frames 19 by means of brackets 20, which are of riangular shape and have secured to their lower faces in-- clined drain-boards 21 to prevent'dirt falling from the run-boards 18 upon the iower bight of the separating apron. Such material is conducted by the drain-boards 21 beyond the edge of the separating apron, where it is discharged through a slot between the drain-boards and the side frames 19.

In order toprovide a platform on which a man may stand while removing the screen frames on thescreen drum and which during the operation of the machine will support the apron and prevent it from saggin in the center, a platform 22 is positione just beneath the upper bight of the separating apron. This platform is made wlth stringers 23 which are suitably secured to lVhile working on the screen drum a person may stand on the platform without injury to the separator apron.

It is usual to provide inclined guardboards above the edges of the separating apron to prevent the peas and other material falling beyond the edges of the apron, but as the edges of the uard-boards were in line with the travel of the apron the mate-' rial falling therefrom was deposited to a considerable depth in a narrow line and peas embedded in the material were carried along therewith over the upper end of the separating apron and were so lost in the chaff. This was particularly true at the feeding end of the machine where large quantities of dirt and loose leaves were dropped from the screen drum immediately upon entering the same. In order to overcome this difficulty the guard-boards 26, mounted on brackets 36 from the sheeting 37, are so arranged that their lower edges are at an angle to the path of travel of the apron, as clearly seen in Fig. 2, the boards being narrower at their upper ends, which serves to spread the deposited material in a broad path over the apron. The material being spread in a thin broad layer instead of a thick narrow line, enables the peas to separate therefrom. V I

To prevent the peas from rolling off of the edge of the apron and to strengthen the apron along its edge and avoid stretching or frilling, a raised welt or bead is formed along the edges. This ridge is preferably formed by means of a rope 27, as shown in Fig. 4:, encased in a strip of-canvas 28 stitched to the hemmed edge of the canvas apron 14, the hem 38 of which being turned under to form a bearing surface engaging the run-boards 18, as shown in Fig. 3.

Beneath the upper end of the separating apron is a chaff and dirt carrier extending lengthwise of the machine and adapted to receive the chaff and dirt as it falls from the apron, such carrier preferably consisting of suitably driven conveyer chains 29 passing around sprockets 30 and connected by cross-slats 31 to push the dirt and chaff along a floor 32. A scraper 33 is hinged to the frame of the chaff and dirt carrier and is yieldingly held against the surface of the separator apron 14 by means of a spring 34 or weight. The scraper 33 is so positioned above the carrier as to cause the material to drop from the apron near the middle of the carrier and so prevent it from falling on the chains. An inclined guard-board 35 on the other side of the carrier frame serves the same purpose of protecting the chains from becoming fouled y the leaves and dirt.

The operation of and the advantages for w the various features of this invention have been stated in connection with the descri tion thereof. They all serve to make t e separating apron more efiicient, more durable and less liable to fouling. The ridged edges of the apron make it possible to use rigid guard-boards sufficiently spaced from the apron to avoid contact therewith and dispense with the necessity for flexible guards that tend to wear the apron on account of the unevenness of the apron and its flopping motion during operation.

What I claim as new and desire to secure by Letters Patent:

1. An inclined upwardly travelling separating apron for viners and the like, means for giving the apron a varying tension to produce a vertical whipping action, the side edges of said apron being free to respond to such vertical Whipping action, and raised flexible ridges at such edges of the apron formed only on the outer surface thereof to prevent the whipping action on the apron from causing the material to be thrown from the edges.

2. An inclined upwardly travelling separating apron for viners and the like mounted to have a varying tension to 've it a vertical jerking motion, and flexib e rid formed in the edges of the apron on t e outer surface only thereof by means of ropes encased in fabric strips and stitched to the edges of the apron.

3. An inclined upwardly travelling separating apron for viners and the like, mounted to have a varying tension to produce a vertical jerking motion, and having its edges free to partake of such motion, flexible ridges formed on the edges of the apron by a rope secured to the outer surface of the apron, and guides on which the inner surface of the edges of the apron may bear.

4.. In an inclined upwardly travelin tated separating apron for viners an like, a rope extending along the outer surface of the unconfined edge of the apron, and a strip of fabric encaslng the rope and stitched to the inwardly turned hemmed edge of the apron.

5. In a separating apron for viners and the like, run-boards on which the edges of the apron bear, and inclined drain-boards between the upper and lower bights of the apron for carrylng material falling from the run-boards beyond the edge of the lower,

bight of the apron.

6. In a separating apron for viners and the like, run-boards on which the edges of the apron bear, a platform beneath the upper bight of the apron and spaced from the run-boards to permit material to fall through the space between them, and innlined drain-boards for conducting such material beyond the edge of the lower bight of the apron.

7. In an inclined upwardly traveling e tated separating apron for viners and the like, an inclined rigid guard-hoard overhanging the edge of the apron and out of contact therewith with its lower edge at an angle to the direction of travel of the apron to spread the material falling therefrom over the apron.

8. In an inclined upwardly traveling agitated separating apron for viners and the like, inclined rigid guard'boards overhanging the edges of the apron andout of contact therewith, with their lower edges direrging toward the upper end of the apron to spread the material falling therefrom over the surface of the apron.

it In an inclined npwardly traveling separating apron tor riners and the like mounted to have a varying tension to produce a jerking action. a chatt and dirt carrier heneath the upper end of the apron. and a yielding FPIIIPQI engaging the lower bight of the apron to scrape material therefrom upon the middle portion of the chat? and dirt carrier.

10 In an inclined upwardly traveling separating apron for vinere and the like mounted to have a varying tension to produce a. jerking action, a chain and slat ehait' and dirt carrier beneath the upper end of the apron, a spring actuated scraper on one side of the carrier engaging the lower hight of the apron to scrape material therefrom upon the central portion of the carrier, beyond the chain on that side of the carrier and an inclined guard-hoard on the other side of the carrier to prevent the chat? and dirt falling on the chain on that. side of the carrier.

In testimony whereof, I afiix In signature, in presence of two witnesses.
